How to get potions?
There are three ways to get potions:
1. Merge gems of the same colour
Different colours give different potions. For example, merging green gems together gives you Slow Motion potion, while merging yellow gives Double Gold.
2. Lock picking
You will sometimes earn potions while trying to open a dungeon door.
3. Spend orbs
You can buy potions any time during an attack by spending blue orbs.
